Photoshop’s new Adobe Camera Raw (ACR) has had a major change in the new version of Photoshop CS5. The sharpening and noise reduction areas have had a major change and improvement. I heve recently tried out the new noise reduction and have found it to perform vastly better than the previous version. The version of Adobe Camera Raw I am using is 6.2.
The section of image below is a 200% crop from a high ISO image from a Nikon D2H. As can be seen from this crop the image shows significant noise.
After loading the image in ACW we can see the following settings in the sharpening and noise reduction areas.
There are sharpening settings for:
- Amount,
- Radius,
- Detail,
- Masking.
There are also Noise Reduction settings for:
- Luminance,
- Luminance Detail,
- Luminance Contrast,
- Color,
- Color Detail.
With the image crop shown above the Noise Reduction settings, were adjusted to reduce the impact of the noise and the resulting image crop below was achaived. As can be seen there is an excellent result obtained with very little loss of detail.

Riverfire, Brisbane, 2010
This image from Riverfire, Brisbane, 2010, was captured using three sererate exposures and merging them together in Photoshop CS5. The following is the sequence I used to obtain the final image.
-
Take three seperate images with the camera on a sturdy tripod, using a remote cable release. Do not move the camera or tripod during this process.
-
Import the three image files into Photoshop ( I did this using the raw files, NEF files as I was using a Nikon camera). Select File/Automate/Photomerge.
-
Select Browse to import the images.
-
Select Auto, do NOT select Blend Images Together, Then select OK.
-
This will then import all the images into Photoshop and merge them all together to allign then up.
-
Then using the LAYERS selections, select each layer seperately and adjust each layer. In this case I had three images which created three layers. I then adjusted the saturation and tones of each layer using Image/Adjustments/Curves.
-
Then individually select each layer and select Screeen mode for each layer.
-
Check that the final image is what you are aiming for.
-
Then select Layer/Flatten Image, this will merge all the layers into a single layer.
-
Do any final adjustments to the final file such as, saturation and exposure and curves.
-
Job completed.
The above method of processing multiple images is much better than doing multiple exposures in camera, as it gives more flexibility in selecting suitable images after the event. Also each exposure which is to be incorporated into the multiple exposure can be individually adjusted and processed before being merged together.

The completed image after the Content Aware has been applied to the image is shown bove, this can be compared to the original image below.
There are two ways to apply content aware. Firstly using the Spot Healing Brush Tool, which is selected from the left menu column as indicted below.
After selecting the spot healing brush tool, Content-Aware is selected from the top bar as shown below.
The areas of the image that require the content aware fill can then be brushed in.
The second method of applying the Content Aware is to select the area you require to fill, then select Edit/Fill and then select Content Aware in the dialogue box. Click OK and the change will be applied to the image.
The original image with the power lines still in the image is shown below. As can be seen by comparing the two images there can be significant improvements.

The above image is a composite image of the two seperate images below. The two images have been seperately opened in Photoshop and placed in seperate layers. The layer with the bird flying has been selected to remove the sky area.
The sky area of the image has been selected using Select/Color Range, using the options available as shown below.
Any areas around the bird can be tidied up using the Quick Selection Tool available on the left side menu bar.
The image of the sky was then selected and modified using levels and curves to improve the tonal range and a slight boost to the saturation was given to improve the overall image.
With Photoshop CS5, there is an enhanced refine edge tool available to help fine tune the edge selections. In this case I selected the View Mode in On Black, here you can try various options. The smart radius feature adapts the selection approach between the bird feathers and the sky. There is also an Erase Refinements tool to remove any unwanted areas from being modified, where you do not want to include areas in the mask, in this image this tool was not needed.
After I was happy with the image selections I flattened the image and then saved it.
